To see the real MTU you have to use "show queuing interface <phys_int>". For example: # sh int e1/45 Ethernet1/45 is up Dedicated Interface Hardware: 1000/10000 Ethernet, address: 8c60.4f96.2cf4 (bia 8c60.4f96.2cf4) Description: storage2-01 *MTU 1500 bytes*, BW 10000000 Kbit,, BW 10000000 Kbit, DLY 10 usec [...] # sh queuing int e1/45 n5k-pg2-a# sh queuing int e1/45 Ethernet1/45 queuing information: TX Queuing qos-group sched-type oper-bandwidth 0 WRR 100 RX Queuing qos-group 0 q-size: 100160, q-size-40g: 100160, *HW MTU: 9216 (9216 configured)* drop-type: drop, xon: 0, xoff: 0 [...] Hope this helps Christophe _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
